Is it a bad practice to use self-signed SSL certificates?
SSL certificates are pretty expensive for individuals, especially if you need to secure different subdomains. I am considering using self-signed certificates, as my primary focus is to secure the connection, and not to authenticate myself.
However, several browsers display nasty warnings when encountering such a certificate. Would you discourage the use of self-signed certificates (for example for small web application or the admin page of a small website) ? Or is it OK in some cases ?
